Internet Security
Discuss what allows Internet access to users, with particular reference to protection against threats: viruses, spamming, and hackers.
In our network design, Internet access will be granted through a centralized point located at the Los Angeles Data Center. Corporate policy dictates that the corporate internet connection is to be utilized for business purposes only, and use for any purpose other than a justifiable business need will result in disciplinary actions, or termination.
To help deter users from violating this policy, we have implemented a corporate firewall at the access point to the internet. To assist in the prevention of attacks from viruses, spam, and hackers, the following measures will be taken.
Ports
Common ports that are related to gaming and personal internet services will be shut down to prevent unauthorized access to the internet. Since our policy will be limited access, with a business need justification for access through a port, most of these ports will already be blocked.
POP3 mail – Port 110
Gaming (Ultima, Quake II & III, Fighter Ace II) – 5001-5010, 7775-7777, 27910-27960, 50000 – 51000
Anti-Virus
Norton Anti-Virus Corporate Edition will be part of the standard build for all PC’s (desktops, laptops, etc), and Servers. LiveUpdate will be employed to insure that timely definition updates take place. During login, a check will be made to verify that the definition files are up to date, if they are not, the user will be n...
It is best to prevent security incidents from occurring in the first place – therefore prevention should be a top priority for the IT staff at CEG. The National Institute of Standards and Technology (NIST) recommends five main categories of incident prevention; risk assessments, host security, network security, malware prevention, and user awareness training (Cichonski P., Grance T., Millar T., & Scarfone K., 2012 p.24). Risks of the various types of possible security incidents should be identified and prioritized based on likelihood and potential harm. Risk assessment should be periodic and ongoing. Host security is achieved by hardening each host on the network. Host hardening includes keeping current on the latest software patches, enabling and monitoring audit logs, and assigning permissions based on a system of least privilege. Network security is primarily concerned with securing the perimeter of the network to prevent unauthorized intrusion. This includes the use of firewalls, intrusion detection systems (IDS), securing VPN, and blocking unnecessary ports. All hosts on the network must run and regularly update malware protection software. And all employees should...
What concerns the government of the United States most is the security of the critical infrastructure from the cyber threats. The nation is depending heavily on the technology in most of its critical sectors to keep it up and running. Thus, this makes its more vulnerable to cyber-attacks from outsiders and insiders. Therefore, its protection must be a priority.

With the rapid development of the technology, Internet has become a significant part in our daily life. The Internet does make our lives convenient, but at the same time, it raises many issues, like Internet violence, Internet fraud and Internet privacy. This report focuses on the Internet privacy issue. While enjoying the benefit, Internet users are asked to offer lot of their person information. Luzak (2014) argues that users should be clearly and comprehensively informed of the use of their personal privacy. He points out that Internet users are lack of information that cookies are set to store their tracks when they surf the Internet. Luzak analyzes the limitation of the current European
Network Security is the protection of the computer’s network though out the entire infrastructure. It can protect very important information and computer files to help prevent theft, spyware, malware, viruses, and more. Depending on if you have a public or private network, can determine what type of security settings you need for your network. All people are different on what they want to have secured or not, but most people do not know how to prevent people or things from getting in their network. “You must have a general understanding of security terminology and specifications as it relates to configuring hardware and software systems.”(Roberts, Richard M. 599). That quote states that by knowing and understanding security terms and specifics, you can
There are three main policies that NPS deals with. The first is connection request polices. This policy “establishes a set of conditions settings used for authentication, authorization, and accounting” (Regan, 2013). The connection request determin...
In today’s society technology is used for everything. With the invention of computers and the internet this open doors to the cyber world. Today you can do almost anything without having to leave your home. The internet gives us the opportunity of shopping online, ordering food online, working from home and video chatting with friends and family across the world. Everyone has a computer and internet access in their homes. While the internet is really convenient it also opens doors for cybercrimes, loss of privacy and the need for computer security.
The history of the internet shows that the internet is not a new medium. The internet was initially created in the 1960's to as a way for the United States to stay connected in case of a nuclear fallout due to the possible consequences of the Cold War. F...
Most of the Internet regulation is imposed by the Government in an effort to protect the best interest of the general public and is concerned with some form of censorship.
ABSTRACT : This paper describes the basic threats to the network security and the basic issues of interest in designing a secure network. it describes the important aspects of network security. A secure network is one which is free of unauthorized entries and hackers. INTRODUCTION
In this new era of the Internet, most people use the Internet to acquire information of one kind or other. But what these people are not aware of is that the Internet is collecting information about them. Every time we get onto the Internet there might be a compromise of privacy of our personal information. The information flows both ways. With every clock of the mouse on a hyperlink, or an addition to the mailing list, someone out there might be gathering information about us. This raises the seriousness of privacy of our information on the Internet.
The security topology will determine what network devices are employed at what points in a network. At a minimum, the corporate connection to the Internet should pass through a firewall. This firewall should block all network traffic except that specifically authorized by the security policy. Blocking communications on a port is simple; just tell the firewall to close the port. The issue comes in deciding what services are needed and by whom, and thu...
Today, society is affected by the many advances in technology. These advances affect almost every person in the world. One of the prevalent advances in technology was the invention and mass use of the Internet. Today more than ever, people around the world use the Internet to support their personal and business tasks on a daily basis. The Internet is a portal into vast amounts of information concerning almost every aspect of life including education, business, politics, entertainment, social networking, and world security. (idebate.com) Although the Internet has become a key resource in developing the world, the mass use of Internet has highlighted a major problem, privacy and the protection of individual, corporate, and even government security . The argument over whether or not the Internet should be controlled by the government has developed into a controversial issue in almost every country in the world.
In our society, there has been a revolution which competes that of the industrial revolution. It is called technological revolution. At the top of the technological revolution is what we call, the Internet. In the following report we will be discussing about what the internet is about in general and how it might be in the future, why it is necessary in our everyday lives, and why has it become so important to everyone (i.e. companies, individuals ).
The Internet has revolutionized the computer and communications world like nothing before. The Internet enables communication and transmission of data between computers at different locations. The Internet is a computer application that connects tens of thousands of interconnected computer networks that include 1.7 million host computers around the world. The basis of connecting all these computers together is by the use of ordinary telephone wires. Users are then directly joined to other computer users at there own will for a small connection fee per month. The connection conveniently includes unlimited access to over a million web sites twenty-four hours a day, seven days a week. There are many reasons why the Internet is important these reasons include: The net adapts to damage and error, data travels at 2/3 the speed of light on copper and fiber, the internet provides the same functionality to everyone, the net is the fastest growing technology ever, the net promotes freedom of speech, the net is digital, and can correct errors. Connecting to the Internet cost the taxpayer little or nothing, since each node was independent, and had to handle its own financing and its own technical requirements.
